I have similar concerns with my 2018 Axis 24.1. I was very disappointed to find that each tv has a short HDMI cable attached in it's respective area, but no routing to a common HDMI connection point/switch to enable connecting all three to my DISH sat box!
I would have to run a HDMI cable out my kitchen window down to the outside TV to have it and the living room sets connected, but it would be just about impossible to route back to the bedroom tv.
My sat box output does have a coax output that I can feed back out thru the kitchen window, then plug in to the external cable connection. By having the bedroom and external sets selecting "cable" rather than HDMI source, it will give me low resolution on the external and bedroom sets...but that is not my goal!!
